4. CIRCUIT DESCRIPTIONS
GRAPHIC EOUALIZER SECTION
A graphic equalizer is a device which divides the
audio frequency band into several segments called
octaves so that the level of each individual octave
can be increased or reduced. The SG-530 divides
reproduced frequencies into 7 octaves with center
frequencies of 60H2, 150H2,
OOHz, 1kHz,
2.4kHz, 6kHz and 15kHz. The level of each
octave can be varied throughout a range of 110 dB,
and the left channel and the right channel can be
adjusted independently.
Further, when the equalizer switch (EQ SW) is
ON, the LEDs built into the level controls (sliding
variable resistor knobs) light to allow the frequency response of each octave to be determined
visually. The equalizer element is an LC series
resonance circuit in which the active element is
an inductor equivalent. This resonance circuit is
connected to the variable resistor linking the
positive and negative input terminals. (See Figure
4-1.)
This causes the impedance of the resonance
circuit and the resistance of the variable resistor to
act as constants for the input circuit and the
feedback circuit. Further, buffer amplifiers are
located before and after the EQ AMP so that the
frequency response of the equalizer element are
not affected by the impedance of audio equipment
connected to the SG-530.
Figure 4-1 shows the equivalent circuit for the
graphic equalizer section. In the area surrounded
by the dotted line, the circuit on the Q1 side of
point A is equivalent to an inductance and a
resistance connected in series. Any required resonant frequency can be obtained by changing the
inductance and capacitance of the series resonance
circuit by varying CI, C2, R3 and R4. With the
SG-530, 7 equalizer elements with different
resonance frequencies are included in one EQ
AMP, and each frequency segmentcan be adjusted
independently. The frequency response of each
octave is boosted when the slider of the variable
resistor is moved toward the minus input side (the
feedback input side) of EQ AMP ICl; conversely,
it is reduced when the slider is moved to the plus
side.
P O W E RS U P P L YC I R C U ! T
As is shown in Figure 4-2, two voltage (+11 V
and - 11.5 V) are supplied by the regulated power
supply of the graphic equalizer section. The LED
set in the knob of each sliding resistor is supplied
with stable current by Q23, so the light emitted
by the LED is steady. Further, the load on Q18
and q2L is light because the LED current is
obtained after full wave rectification. Q23 goesON
when the EQ switch is tumed ON to release GND
on the base side, and the LED lights when Q23
goesON.

o TAPE switch (S1-3)
This switch selects between a program source or
a tape playback (or REC monitor) signal.
. EO REC switch (S1-1and S1-2)
Turning this switch on causes an equalized
program source signal to be output to the REC
terminals.
o EO switch (S1-1)
This switch determines whether or not a signal is
to be equalized; when this switch is OFF, the
equalizing circuit is by-passed and the input
signal is connected directly to the output terminals.
